These examples use the formulas of the area and alums of circles, spheres, and cones. These techniques are applicable to cubes, cylinders, rectangles, triangles, prisms and pyramids using their respective formulas. I encourage beginners to organize the given information by these 5 steps:
1: Find what?
2: Given what?
3:What is the connection between these?
4:Implicity differentiate something
5:Plug in what you know, solve for what you don't know
